FLY-TRAP.

Application filed October 17, 1914.

To all whom it may concern Be it known that I, SAMUEL T. Jnrrnnis, asubject of the King of Great Britain, residing at Hopedale, in thecounty of Worcester and State of Massachusetts, have 1nvented certainnew and useful Improvements in Fly-Traps, of which the following is aspecification.

This invention relates to insect traps, and more particularly relates toa device of this character adapted to attract such insects as theordinary household fly, aiparticular aim being to afford a trap of thistype in WlllCh ingress shall be comparatively easy and egresspractically impossible.

A more specific object is to provlde in a trap of the type set forthmeans for removably nesting conical leading funnels in such manner as toutilize a flys natural tendency to a certain mode of progression inorder to assure its entrance into the trap.

A specific object of equal importance with the foregoing is to provide atrap of the character described which shall be constructed with suchregard to proportion, number and arrangement of parts as to render itcapable of being cheaply manufactured as well as durable and eflicientin operation.

The above and additional objects which will become apparent as thisexplanatory description proceeds, are accomplished by such means as areillustrated in the accompanying drawings, described in the followingspecification, and then more particularly pointed out in the claimswhich are appended hereto and form a part of this ap- WVith reference tothe drawings, wherein there is illustrated the preferred embodiment ofthis invention as it is reduced to practice, and throughout the severalviews of which like characters of reference designate similar parts:Figure 1 is an elevational View of the trap showing the manner in whichan insect may readily gain ingress thereto, Fig. 2 is a bottom plan viewof the removable globe trap, Fig. 3 is a sectional view taken on avertical plane through the device illustrating the method of seating theglobe trap, and Fig. is an enlarged sectional detail illustrating thehinged closure wherethrough the trapped insects may be removed and thespring catching means therefor.

Specification of Letters Patent.

SeriaI No. 867,195.

In a preferred embodiment of this invention as illustrated, there areprovided a base portion terminated as a whole by the nu' prises theannular ring 9 provided with a number of lateral projections 10 of asimilar size to formlegs or supports therefor, and has its upper edgedownwardly bentas indicated at 11 in order thatit may be crimped overthe lower edge of the truncated funnel 8 which, in common with thefunnel 7 and globe 6 is formed of a forami nous material preferably of alight wire netting and of the frusto-conical shape illustrated havingits upper truncated edge bound as indicated at 12. Midway between theupper and lower edges of the cone 8 is horizontally secured thesubstantially L- shaped flange 13 which is annular and completelysurrounds the cone with its extending portion in a horizontal plane.

The globe 6 is connected to the funnel 7 as indicated in Figs. 2 and 3,the meeting edges of which as indicated at 14: being both clampinglysecured under the bent ver upper edge of an annular flange 15 which asclearly illustrated in Fig. 3 is of such size as to snugly fit aroundthe cone 8 when clearly positioned upon the flange 13. This constructionspaces the nesting cone 7 from the entrance cone 8 in a manneradvantageous to the trapping of insects as will be hereinafter morefully explained. The upper portion of this inner cone 7 communicateswith the interior of the globe 6 by means of a metallic nipple 7aifording a passageway of such size as to easily accommodate one fly inits upward travel.

The closure for the globe 6 is illustrated in detail in Fig. 4:, and asshown, consists of crimped annular gripping ring which is clamped uponthe upstanding edges of the foraminous material composing the globe 6,the latter being cut at this point. To the ring 16, there is hinged asindicated at 17, a closure cap 18 which is provided at one point withthe spring catch 19 adapted to engage in a suitable notch 20 formed inthe immediately adjacent portion of the ring 16 in the obviousmanner,'said catch being elongated as shown at 21 to provide a readymeans for accommodating the operators fingers when it is desired todisengage the catch.

In operation, it will be seen that a suitable bait may be positioned atany convenient point within the trap when the latter is as sembled asshown in Figs. 1 and 3, such as within the globe 6 at the juncture ofthe latter with the inner funnel 7 or upon the flanges 15 of theremovable portion. Flies attracted by this bait. will travel up theinner portion of the base cone 8 until reaching the comparatively widemouth 12 whence their more probable course of action will take them downthe sloping outer sides of the base funnel until reaching the flange 15since what may be termed the natural progress of a fly is usuallyconfined to a movement essentially forward although generally diagonallyto some immediately previous line of travel, it will be apparent thatthe forward procedure of the fly no matter how diagonal will carry himacross the flange 15 and' up the inside of the trap funnel 7 until thepassageway 7 is eventually passed and the fly has gained entrance to theinterior of the globe 6 from whence it is practically impossible for itto find egress. When it is desired to remove the flies thus trapped theupper portion maybe lifted from the flange 13 and the flies removed byway of the removable closure 18 and the globe then replaced in itsformer position. It will thus be seen that after the fly has passed thebroad entrance 12 that he is practically as good as trapped due to thespacing of the interior cone from the base cone in the manner effectedby the flanges 13 and 15. While in the foregoing however, there has thusbeen illustrated in the drawings and described in the specification suchcombination and arrangement of elements as constitute the preferredembodiment of this invention, it is desired to emphasize the factmounted on said ring, an angular flange ring resting upon said funneladjacent the cen: tral portion of the same, an angular supporting ringhaving one angle resting upon said flange, and a globe trap membersecured to the remaining angle of said angular supporting ring andprovided with a normally closed discharge openin 2. An insect trapcomprising a truncated foraminous funnel, a supporting ring for saidfunnel provided with depending legs, a ring clamped upon said funnel, asupporting ring resting upon the last mentioned ring and having anupturned edge, a second truncated foraminous funnel secured to saidupturned edge and extending above the first mentioned funnel, a nipplesecured upon the upper end of the last mentioned funnel, a

foraminous globe secured to said upturned f edge and inclosing thesecond mentioned funnel, said globe having a discharge opening formedtherein, and means for normally closing said discharge opening.

In testimony whereof I ai'fix my signature in'presence of twowitnesses.v
